This is a Mahjong game of the Japanese style rule.
Mahjong is the game to finish four Melds and one Pairs.

Example: [1, 2, 3][6, 6, 6][6, 7, 8][N, N, N][4, 4]

However, there is a hand not approved when Chi, Pon, and Open Kan.
Please note whether there is a hand when you do 1 and 9 in Chi and Pon.
In the rule of the japanese mahjong, one or more hands are necessary.
The hand can be made by paying 1,000 points and doing Reach.
However, when Chi, Pon, and Open Kan are done, Reach cannot be done.
If it is a closed hand, high point will be obtained.
About Lost Hand. A hand that is Waiting, but cannot be won off someone else's discard due to the fact that the owner of the hand already threw a winning tile in their own discard.
Lost Hand if one in all winning tiles are here even if discard doesn't do the tile which it wants to do. But, self-draw is possible even with Lost Hand.
The knack is that Ron is never done by the other party.
Ron is never done with the tile that does Discard.
Please reason the Hand from other party's Discard and win.

Very Solid Japanese Mahjong!

While I'm far from a Mahjong expert, the AI sure seems competent and can actually score some pretty specialized hands. The interface is very intuitive and I love how it uses (or at least gives the option for) the Western tile set. It also keeps decent statistics. Some of the documentation suffers from a bit of poor translation but it's still fairly followable.

Best I’ve seen in a long time

Whilst not the greatest digital version of mahjong I’ve seen, it’s far and away the best version using Japanese scoring in the American App Store. Not only that but it’s the simple things like actually using the correct Japanese terminology (pon, kan, chi, etc) instead of Chinese terms (pung, kong, chow, etc) which makes a real difference when playing. I would like to see an English version of the rules and scoring but if you already understand this is a good app for you.
